HORSE POWER.

SPECIFICATION forming part of Letters Patent No. 297,825, dated April 29, 1884.

Application filed February 26, 188 1. (No model.)

1'0 all whom it may concern.-

Be it known that I, J OHN T. MOCARNEY, a citizen of the United States, residing at, lumbus Junction, in the county of Louisa and State of Iowa, have invented certain new and useful Improvements in Horse-Powers; and I do declare the following to be a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form apart of this specification.

Figure 1 of the drawings is arepresentation of this invention, and is a vertical section. Fig. 2 is a detail view showing brake.

This invention has relation to friction-brakes for that class of horsepowers which have the 'master-wheel formed with a central block or hub seated on a perpendicularcenter-pin; and the invention'consists in applying on the lineshaft, under the center-pin,.a friction-wheel, rigidly cemented to and turning with the lineshaft, and in proper relation to this frictionwheel a band-brake or friction-brake having an operating arm extending upward through a passage in the center-pin, and terminating in a handle Within easy reach of the driver, all as hereinafter set forth.

In the accompanying drawings, theletter A designates the master-Wheel, and Bthe hub or center bearing thereof,proj ecting upward from the bridge-beam C, which is secured to the timbers of the frame D. The center-pin is 3 5 provided with a way or passage, 6, in its center or side, which is continued downward through the bridge-beam and central supports.

F represents the line-shaft, having at its op- .posite ends the bevel-pinions .or bevel-wheels 0 g, which engage the bevel-wheels h, the shafts of which extend upward to bearings of the bridge-beam and carry the pinions k, which engage the master-wheel. On the line-shaft,

vertically under the center-pin, is keyed a friction-wheel, L, and around the under side of this wheel extends the friction band or brake Z, which is provided with an arm, V, which extends upward through the passage 6 of the centerpin, and is provided at its upper end, which projects above the master-wheel, with an operating-handle, whereby the brake canbe brought into engagement with the friction-wheel by the driver whenever it is necessary to lessen the speed of themachine or to stop The arm may be made in screw threaded bearing connected to thecenter-pin, said bearing engaging the thread of the screw, so that when turned by means of the handle on its end it will raise or lower the brake, applying it or taking it off, as may be required.

I am aware that it is not new to provide a horse-power with a master-wheel having a hub bearing on a center-pin with a perpendicular .passage for a rod to operate a friction-brake on the line-shaft, and therefore do not claim such construction, broadly.

Having described this invention, what I claim, and desire to secure by Letters Patent,

In a horse-power, the combination, with the master-wheel having acentral block or hub seated on a perpendicular center-pin, of the line-shaft F,friction-wheel L, rigidly connected thereto under the center-pin, as shown, the frictionbrake Z, constructed as described, having its operating-arm V extending up through a passage, 6, in the center-pin, and terminating in a handle, substantially as speci- 8o fied.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN T. MOCARNEY.
